android获取手机ip地址wifi状态与非wifi状态
方法一(只适合wifi状态):
public static String getIp(Context contxext) { WifiManager wm = (WifiManager) contxext.getSystemService(Context.WIFI_SERVICE); // 检查Wifi状态 if (!wm.isWifiEnabled()) wm.setWifiEnabled(true); WifiInfo wi = wm.getConnectionInfo(); int ipAdd = wi.getIpAddress(); String ip = intToIp(ipAdd); return ip; }
public static String intToIp(int i) { return (i & 0xFF) + "." + ((i >> 8) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." + (i >> 24 & 0xFF); }
方法二(通用ipv4地址):
private String getIp() { try { for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) { NetworkInterface intf = en.nextElement(); for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) { InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) { return inetAddress.getHostAddress(); } } } } catch (SocketException ex) { ex.printStackTrace(); } return null; }
方法三(通用ipv4与ipv6)
/** * Get IP address from first non-localhost interface * * @param useIPv4 true=return ipv4, false=return ipv6 * @return address or empty string */ public static String getIPAddress(boolean useIPv4) { try { List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces()); for (NetworkInterface intf : interfaces) { List<InetAddress> addrs = Collections.list(intf.getInetAddresses()); for (InetAddress addr : addrs) { if (!addr.isLoopbackAddress()) { String sAddr = addr.getHostAddress().toUpperCase(); boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr); if (useIPv4) { if (isIPv4) return sAddr; } else { if (!isIPv4) { int delim = sAddr.indexOf('%'); // drop ip6 port suffix return delim < 0 ? sAddr : sAddr.substring(0, delim); } } } } } } catch (Exception ex) { } return ""; }
